Assesses, through a streamlined risk assessment process, potential human health and ecological risks associated with mining-related contamination at the Monumental, Cap Martin, Sheridan, Tillicum, and Central Mines (collectively called Granite Creek Mines). Arsenic and lead were identified as contaminants with carcinogenic risk predicted from exposure to arsenic-impacted surface water and soil/wasterock. Soil and wasterock threaten ecological impacts for primary plants and terrestrial invertebrates, and surface and pore water similarly pose a threat to aquatic life and wildlife. An Engineering Evaluation/Cost Analysis (EECA) is recommended, along with a data gap investigation.

Documents Site Inspection performed by EA Engineering at five Granite Creek Mines: Monumental, Cap Martin, Sheridan, Tillicum, and Central. The objectives were to access the immediate or potential threat posed by wastes at the site to human health and the environment, and to collect information to support a CERCLA decision, including background research and file review; onsite and offsite reconnaisance; and collection and analysis of soil, waste, surface water, pore water, sediment, plant tissue, and benthic macroinvertebrate samples. Based on the elevated concentrations of metals detected in onsite soil and waste rock samples at all five mine sites, as well as onsite surface water samples collected at the Monumental Mine, an Engineering Evaluation/Cost Analysis (EE/CA) is recommended.

Documents, pursuant to the Guidelines of the National Oil and Hazardous Substance Contingency Plan (NCP), the decision to initiate a CERCLA investigation in nine locations at the Granite Creek Tributary Mines site. A Site Inspection has determined that a hazardous release has occurred, and a human health and ecological risk assessment has been performed and acceptable exposure has been exceeded. Identifies possible threats to nearby human populations, animals, the food chain, soils, and drinking water.

FEIS analyzes five alternatives seeking to make management, utilization, and disposal of natural resources compatible with the HCNRA Act. Record of decision announces selection of the preferred Alternative E-modified, which continues the management direction in the Forest Plan, but with specific changes designed to address the need for change. Includes emphasizing maintaining the rustic and primitive nature of the area while restoring the natural role of fire and maintaining vegetative conditions within HRV.

Announces decision to implement Alternative 5 of project EA, to restrict motorized use in the Sled Springs area to designated routes.
Upon establishment of the trail system, or implementation of the Forest-wide Travel
Management Plan, which ever comes first, off-trail travel by motorized vehicles will no
longer be authorized except for snowmobile use in the winter. The OHV trail system will
include 156 miles of designated roads and trails for use by all-terrain vehicles and
motorcycles (Oregon class 1 and 3 vehicles, described as OHV vehicles henceforth). Of this
156-mile road and trail system, full-sized vehicles (Oregon class 2 vehicles) are authorized
to travel on 71 miles of existing roads. Convert 60 miles of existing roads into OHV-only
trails and construct approximately 25 miles of new OHV trail as connections between
existing roads to create logical riding loops.

Proposes to establish a 166-mile OHV trail system in the Sled Springs area. This OHV trail system
would be for all-terrain vehicles and motorcycles. The proposal consists of converting 71
miles of existing roads into OHV-only trails, converting an additional 77 miles of existing
roads into routes available for both full-sized vehicles and OHVs, and constructing
approximately 18 miles of new OHV trail as connections between existing roads to create
logical riding loops. This alternative also includes the placement of five OHV bridges where trails cross
streams.

The Upper Grande Ronde Mine Tailings Restoration Project would remove and/or redistribute mine
tailings as far away from the wetted edge of the upper Grande Ronde River as possible. A total of 18 sites would have mine tailings removed or redistributed for an approximate total of
46,964 yards. All of these sites are located within the floodplain of the upper Grande Ronde River
(approx. 2.5 stream miles) and East Fork Grande Ronde River (approx. 25 mile). Wood
would be placed within the entire 4.7 miles of the upper Grande Ronde River. Two roads and two
dispersed sites would be obliterated. Six other dispersed sites would continue to provide recreation,
but would have defined access points through strategic boulder placement. Seeding and planting
would occur through out the entire project area.
